Description
Technical Field
The invention mainly relates to the technical field of cable processing, in particular to a twisting device and a twisting method of an aluminum alloy photovoltaic cable.
Background
The aluminum alloy power cable is a novel material power cable which takes AA8030 series aluminum alloy materials as conductors and adopts special rolling forming molded lines to twist, annealing and other advanced technologies, the alloy power cable overcomes the defects of the prior pure aluminum cable, the electric conductivity, creep resistance, corrosion resistance and the like of the cable are greatly improved although the electric conductivity of the cable is not improved, the continuous stable performance of the cable can be ensured when the cable is overloaded and overheated for a long time, and the AA-8030 series aluminum alloy conductors are adopted, so that the electric conductivity and the high temperature resistance of the aluminum alloy cable can be greatly improved, and meanwhile, the problems of the pure aluminum conductors, the creep resistance and the like are solved.
In order to improve the softness and integrity of the electric wire and the electric cable in the processing process, more than 2 single wires are needed to be interwoven in a specified direction, namely, the electric cable is twisted, in the prior art, the twisted electric cable generally needs to pass through special strander, such as cage strander, disc strander, fork strander, frame strander and the like, but the strander has a plurality of problems in the use process, taking the most commonly used frame strander at present as an example;
the problem is that the cost is high, the adaptability is poor, the cost of one frame strander is generally 20-25 ten thousand, the number of cable wire reels carried by the frame strander is constant, for example, 20 wire reels can be carried by the frame strander of 4*5, when cables of factories are strander, the frame strander of 4*5 is insufficient when required single wires exceed 20, the frame strander with higher specification needs to be purchased, then the cost is increased again, and when required single wires do not exceed 20, the frame strander of the whole 4*5 and related machines need to be started, so that the power consumption cost is increased;
the second problem is that in the paying-off process, the residual wire quantity of the cable is smaller and smaller along with the time, the thickness of the wire spool is reduced, so that the threading distance and the distance are changed, especially for a frame type stranding machine, the wire spools are placed side by side, contact and friction are easy to occur among single wires in the paying-off process, the wire tension is also continuously changed, larger abrasion is easy to occur when the cable passes through the wire spool, and the quality of the cable after subsequent stranding is influenced;
the paying-off wire spool pay-off is not easy to perceive when the paying-off wire spool pay-off is out of the way, the paying-off wire spool pay-off is evenly gathered at the center of the frame type wire stranding machine and then is fed outwards, an operator is not easy to detect the problems of loose wire, even broken wire and the like, and especially when a safety fence is arranged outside the frame type wire stranding machine, the paying-off wire spool pay-off is not easy to observe and monitor, and the quality of a final cable finished product is seriously affected;
the fourth problem is that when the frame stranding machine is used for stranding, the pay-off reel rotates along with the stranding, and the stress generated by the torsion of the single wire is caused, so that the stranding has the tendency of rebound and loosening, the elastic deformation is easy to occur, and the stability of the final stranding structure is influenced.
Besides the problems, the stranding machine needs to drive a plurality of wire reels to rotate at a high speed, has certain potential safety hazards, generally needs an external safety fence to ensure the safety of the device during operation, and meanwhile, when the stranding machine loads the wire reels, besides the need of factory roof truss transportation, an additional feeding device is needed to lift the wire reels and load the wire reels into the stranding machine, so that the workload and the device cost are further increased.
